Abstract: A method of detecting an event in a structure using a device having sensors and at least one actuator includes sending a signal from the at least one actuator encapsulated in the device, returning a reflected wave signal from the event to each of the sensors in the device, determining a respective duration of time for which the signal travels from the event to each of the sensors, and calculating a location of the event by using differences in the respective durations of time for which the signal travels from the event to each of the sensors to determine an angle and a distance at which the event is positioned.

Abstract: A device for use in detecting structural damage comprises at least one piezoelectric wafer including a sensor, and an actuator in-plane with the sensor. At least one of the sensor and the actuator at least partially surrounds the other of the sensor and the actuator such that the piezoelectric wafer provides radial detection of structural occurrences in a material.

Abstract: A device for use in detecting an event in a structure comprises a sensor encapsulation, the encapsulation containing a sensor, an actuator positioned substantially in-plane to the sensor within the housing and a printed circuit board in communication with at least one of the sensor and the actuator. the printed circuit board includes a microprocessor constructed and arranged to collect data from at least one of the sensor and the actuator, a signal generator constructed and arranged to provide excitation to at least one of the sensor and the actuator, and an amplifier to condition the excitation.

Abstract: A molded pad for mounting electrical equipment including a platform of a first material having one surface for carrying electrical equipment; and at least one reinforcing element of a second material integrally molding in the platform for increasing the stiffness and bending strength of said platform.

Abstract: A flyer assembly is adapted for launching with, transit in, and deployment from an artillery shell having a central void region extending along a ballistic shell axis. The flyer assembly includes a jettisonable shroud and a flyer. The shroud extends along a shroud axis, and is positionable within the central void region with the shroud axis substantially parallel to the shell axis. The flyer is adapted to withstand a launch acceleration force along a flyer axis when in a first state, and to effect aerodynamic flight when in a second state. When in the first state, the flyer is positionable within the shroud with the flyer axis parallel to the shroud axis and the shell axis. The flyer includes a body member disposed about the flyer axis, and a foldable wing assembly mounted to the body member. The wing assembly is configurable in a folded state characterized by a plurality of nested wing segments when the flyer is in the first state.
